Which answer choice is correct ?

P=Q

Step-by-step explanation:

The angles of a triangle should add up to 180 Degrees.To figure out what is true about the values we need to solve for both angles.

To solve for P we need to do 80+20=100 and now we subtract the degrees we already have from what we need 180-100=80 P=80

Now we do the same for Q. 45+55=100 180-100=80  Q=80

We know that P=Q This is also symmetric property which you'll probably learn later on.

step-by-step explanation:

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
